PROCESS OF MAKING EMBROIDERY ORNAMENTATION.

Specification of Letters Patent. Patented July 10, 1917- Originalapplication filed June 29, 1914, Serial No. 848,022. Divided and thisapplication filed December 19, 1914. Serial No. 878,095. 7 i

To all whom it may concern: Be it known that I, Runonr Lone, a citizenof the United States, and a resident of" J enkintown, Montgomery county,Pennsyl- 5 Vania, have invented an Improved Process of Making EmbroideryOrnamentation, '(being a division of my application for patent filedJune 29, 1914, Serial No. 848,022,) of which the following is aspecification.

My invention relates to ornamentation effected by embroidery stitching,and comprises an improved process or method of producing a seam or otherornamental eii'ect forv sewed articles, which seam is preferablycircular in outline and with which I combine a novel ornamentation oreffect in the form of a central knot or raised portion; the Wholeconstituting a representation of large embroidered buttons or circularflower-like effects, simulating daisies and the like.

An important feature of my present invention is the method of producingthe raised center or knot in connection with the novel character ofembroidery or embroidered seam forming the subject of my invention.Surrounding this raised center are a plurality of rows of stitches whichare substantially radial. The raised center may overlap the innerannular row. of radial stitches, or a space of plain fabric may be leftbetween this raised center and the in nermost row of stitches. Inaddition the two sets of radial stitches overlap each other and theeffect produced when threads of different colors are employed is highlyornamental.

My present invention comprises the method or process of making theimproved embroidery or embroidered seam.

will be more fully described hereinafter, reference being had to theaccompanying drawings, in which:

Figure 1, is a view of the obverse side of one form of seam made inaccordance with the process forming the subject of my invention, showingthe means employed in laying the several sets of stitches;

Fig. 2, is a View of the reverse side of the seam shown in Fig. 1;

Fig. 3, is an enlarged sectional view on the line III-III, Fig. 1,showing the needles and the rotating presser foot;

of stitches 5 These and other features of my invention.

and by causing the stitches of one .Fig. 4, is a view illustrating amodified form of embroidered ornamentation within the scope of myinvention;

Fig. 5, is a view of the reverse side of the embroidery shown'in Fig.4C, and

, Fig. 6, is a sectional view on the line VI VI, Fig. 4.

In the formation of the embroidery or embroidered seam forming thesubject of my present invention, I employ a sewing machine with aplurality of vibrating needles 1, 2 and 3, which needles are set in linewith each other and vibrate in a single plane coincident with the planeof their position, and such machine is equipped with mechanism in theshape of a rotating fabric moving device whereby the material operatedupon may be turned with respect to a predetermined center whilethe-needles are vibrating and laying the desired stitches; the rotativemovement of the fabric with respect to the vibrating needles, while thelatter are laying their stitches, being wholly under the control ofthe'operatoii WVhile the fabric material is being turned, the stitchesfrom all three needles are laid in a radial direction with respect tothe predetermined center, and this center will beat some pointintermediate the throw of the end needle 3.

By this means, I am able to form a seam which is preferably circular,which consists radiating from a common predetermined center and formingan outer a11- nular row or series; stitches 6 radiating from the samecenter and set inwardly with respect to and directly adjacent thestitches 5; overlapping the same in fact, and a third set of stitches 7which cross each other over the common predetermined center as thefabric is rotated and result in the formation of a central knot for theornamental effect desired, which center is composed of stitches raisedmaterially higher than either of the annular rows or sets of stitches, 5and 6.

It will be understood, of course, that each needle will lay the samenumber of stitches, of the needles to cross the predetermined center ofthe object being formed, the height of such center will naturally beraised. The respective stitches 5, 6 and 7 showing on the face of thefabric have pairs of loops 5*, 6 'and 7 disposed on the under side ofthe same, and these several pairs or sets of loops are caught by asingle shuttle thread 8.

In the form of ornamentation shown in Figs'l, 2 and 3, the inner raisedknot or center is directly adjacent the inner ends of the intermediateset'of stitches.

In {theform of ornamentation shown in .No. 809,798, and as indicated inFig. 3, of

the present drawings by broken lines. These means IHZLY'COIHPIISS afixed carrier member 10, having a friction member 11 rotatably supportedby said carrier and provided with a ball bearing; the friction memberengaging the fabric and turning with the latter around the vibratingneedles as the operator moves thetambour frame in which the fabric isstretched. This fabric moving device is adjustable so as to change thecenter of the same with respect to the throw tation of varioussizes.

of the needles and effect circular ornamen- The needles may also beset'in different relations with respect to each other; changes'in thethrow of the shuttle being correspondingly-effected.

In order to accommodate the raised center made by the stitches 7 duringthe formation of the same, the presser foot 12 is'provi-ded with anenlarged space 1-3 at the outer end of the slotted portion accommodatingthe needles. This presser foot is employed solely to hold the fabricwhile the needles are in the same to insure proper coaction of theshuttle thread and is raised when the needles are raised; having nofeeding or other moving effect 'upon the fabric which is wholly underthe control of the operator.

I claim:

1. The process of producing circular embroidery ornamentation, whichconsists in disposing upon a piece of material a plurality of annularrows or sets of radial stitches formed by continuous needle threads andlaid by vibrating thread-carrying nnplements, simultaneously rotatingthe fabric on an axis that is crossed by the path of the vibratingthread-laying implements whereby the stitches are laid upon the fabricin such manner that portions of said stitches will cross each other atthe center of the embroidery ornamentation formed by the stitches andform a rounded mass projecting above the surface of the fabric and therest of the stitches thereon.

2. The process of producing circular embroidery ornamentation, whichconsists in disposing upon apiece of material. a plurality of annularrows or sets of radial stitches formed by continuous needle threads andlaid by vibrating thread-carrying iinplements, simultaneously rotatingthe fabric on an axis that is crossed by the path of the thread-layingimplements whereby the stitches are laid upon the fabric in such mannerthat portions of said stitches will cross each other at the center ofthe embroidery ornamentation formed by the stitches and form a roundedmass projecting above the surface of the fabric, the balance of thestitches extending radially from said raised center and lying in annularrows independently of said raised center.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
